Happiness can be achieved in life by getting your dreams realized. Gooseberries may be hard and sour for Ivan but they were delicious for Nicholai. Happiness differs from person to person. One man’s meat is another man’s poison and one man’s religion is another man’s madness. There are no common criteria for happiness. Prayer, sacrifice, fasting and abstinence may make some people happy. But others feel happy when they are rich and successful.
